In case it helps you to know this, I'm looking into a similar problem in 2.5.57-58 which may be related to what you (Felix) are reporting. For some reason that I haven't figured out, USB keyboard and mouse that are recognized in 2.5.56 are not recognized by 2.5.57 or 2.5.58, even though lsusb sees them. This is the case on the two different systems that I tried (with a different keyboard and a different mouse). There were no changes to drivers/acpi between 2.5.56 and 2.5.57, and booting with acpi=off does not eliminate this problem. There were few changes to usb between 2.5.56 and 2.5.57. So, I suspect that USB no longer working is a side-effect of some other change. Adam J.
